Cary Products is a plastic louvers manufacturer with over 75 years of experience, supplying custom and proprietary louver components to manufacturers in the automotive, HVAC, construction, agriculture, and energy industries. As a dedicated plastic louvers manufacturer, we produce every component using precision injection molding at our ISO 9001:2015-certified facility in Hutchins, Texas. Our louvers are available in standard configurations or fully customized to your dimensional, material, and performance requirements.
Whether you need a standard rectangular louver for a high-volume application or a winged louver engineered for a specific airflow target, our team delivers it – on time and to spec.
Â
Plastic Louver Product Types
Cary Products produces four main louver configurations. Each is available in standard sizes or custom dimensions, and all are manufactured to the same ISO 9001:2015 quality standard.
Â
Rectangular Louvers
Rectangular louvers are the most widely used configuration across HVAC, construction, and commercial applications. These louvers offer consistent airflow performance and suit high-volume production requirements well.
Â
- Available in fixed standard sizes and custom dimensions
- Suitable for wall, ceiling, and equipment panel applications
- Compatible with multiple thermoplastic materials
- High-volume production capacity
Round Louvers
Round louvers work well in applications that require circular or curved mounting surfaces, including automotive and HVAC ducting assemblies. Cary Products produces round louvers in standard diameters and custom sizes to match your equipment specifications.
Â
- Standard and custom diameters available
- Common in automotive, HVAC, and industrial ventilation applications
- Injection molded for consistent dimensional accuracy
Winged Louvers
Our winged louver design improves airflow efficiency by directing air movement along a defined path. This configuration works particularly well in HVAC and MVAC applications that require controlled directional airflow. For a deeper look at the engineering behind winged louvers, see our article on HVAC component efficiency.
Â
- Engineered blade geometry for optimized airflow direction
- Used in automotive HVAC systems, commercial ventilation, and equipment cooling
- Available in standard and custom configurations
Custom Plastic Louvers
For applications with unique dimensional, geometric, or material requirements, Cary Products develops fully custom louver designs. Our engineering team works with clients from concept through production tooling, producing custom molds that meet exact specifications.
Â
- Custom dimensions, blade angles, and mounting configurations
- Engineering and DFM support included
- In-house tooling capability for new custom mold development
- Minimum volume requirements vary by project — contact us to discuss
Louver Applications by Industry
As a plastic louvers manufacturer serving multiple sectors, Cary Products produces components that meet the specific airflow, durability, and environmental requirements of each industry. For reference on ventilation performance standards in HVAC applications, see the ASHRAE standards library.
Â
Automotive & MVAC – Dash vents, HVAC ducting outlets, cabin air distribution, underhood ventilation.
HVAC & Commercial – Wall registers, ceiling diffusers, equipment enclosure venting, air handling units.
Construction – Building ventilation panels, crawlspace vents, mechanical system components.
Agriculture – Equipment cab ventilation, engine cooling panels, outdoor enclosure venting.
Energy – Control panel venting, enclosure airflow management, industrial equipment cooling.
Â
Materials & Performance
Cary Products selects thermoplastic materials for louver production based on the application’s temperature range, UV exposure, chemical environment, and structural requirements. Common louver materials include:
Â
- ABS: General-purpose applications, good impact resistance and surface finish
- Polypropylene (PP): Chemical resistance, lightweight, suited to HVAC and outdoor applications
- Nylon (Polyamide): Higher temperature applications and structural demands
- Polycarbonate (PC): Impact resistance and applications requiring dimensional stability
Material choice affects part performance, tooling design, and cycle times. Our engineering team advises on the best material for your specific louver application during the design phase.
Â
Custom Louver Options
Every louver we produce offers customization to meet your project requirements. Specifically, options include:
Â
- Dimensions: Custom length, width, depth, and blade spacing
- Blade angle: Fixed or adjustable blade configurations
- Mounting style: Flange, flush-mount, or snap-fit options
- Color: Custom color matching available
- Material: Selected based on application requirements
- Branding: Part marking or identification features available on request
For new custom designs, our engineering team provides design-for-manufacturability review, prototype support, and integrated tooling design before production begins.

Frequently Asked Questions About Our Plastic Louvers
What louver sizes does Cary Products offer?
We offer both standard and custom sizes. Standard configurations cover a range of fixed dimensions. For non-standard sizes, our team develops a custom solution. Contact us with your target dimensions to get started.
Â
Can Cary Products match a specific color or material?
Yes. We produce louvers in custom colors and a range of thermoplastic materials. Selection depends on your application requirements, including temperature range, UV exposure, and structural load. Our engineering team will advise on the right specification.
Â
What is the minimum order quantity for custom louvers?
Minimum order quantities vary depending on whether tooling exists. For existing tooling, minimums are lower. For new custom molds, there is typically a tooling cost and a minimum production volume. Contact our team to discuss your project.
Â
How long does it take to produce custom louvers?
Lead times depend on whether new tooling is required. Runs using existing tooling are typically faster. New custom designs that require new mold development include tooling production time in the lead time. Contact us for a project-specific timeline.
Â
Are Cary Products louvers ISO 9001:2015 certified?
Yes. All louver production at Cary Products operates under our ISO 9001:2015-certified Quality Management System. Every part is produced, inspected, and delivered according to our documented quality controls.
Â
Can Cary Products supply louvers for automotive OEM applications?
Yes. We have extensive experience supplying louver and air movement components to automotive and MVAC manufacturers. Our quality system and production capabilities meet the volume and consistency requirements of OEM supply chains.
